Avocadian (noun) (/ævə’keɪdiən/, or more rarely, /ɑ:və’kɑ:diən/)
Avocadian refers to people who are largely ignorant about language in general but still like to “inform” people about language. Some are rather belligerent in their ignorance and won’t accept any criticism or correction. It also describes any so-called “language troll” who is either trying to mislead, misdirect or misinform genuine language enthusiasts. This word is a pejorative for anyone who wishes to knowingly mislead people as to the true origins of words, terms and languages.
